While winterizing the engine I’ve noticed something unusual. With engine warmed up and running connected to a garden hose with earmuffs I switched to the bucket filled with antifreeze positioned on the swim platform. Reconnected the hose from the bucket to earmuffs (15 seconds process) I expected for the water pump to start pumping the antifreeze right away. Learning from the past that with BIIIs I need to apply more throttle, to provide more circulation since there’s no impeller in the outdrive like in Alpha-1. So I had raised the RPMs, but still no suction. Applied more and very slowly the antifreeze started to be pumped from the bucket. The problem is that a WHITE SMOKE started to come out from the exhaust. I asked my wife to give me a signal when the pink stuff will start to come out from the exhaust while I’m working the throttle and watching the bucket level. The antifreeze level in the bucket started getting low, but instead of the clear pink going out of the exhaust it was a mix of white smoke and dirty water (just a little bit of pink). As soon as the bucket got almost empty I turned off the engine.
Since the antifreeze was pumped out of the bucket I’ve concluded that the engine should of gotten enough of the pink stuff. But, I ended up with two concerned items:
Any advice is greatly appreciated.
Thanks,

Since the antifreeze was pumped out of the bucket I’ve concluded that the engine should of gotten enough of the pink stuff. But, I ended up with two concerned items:
- Why did I see the white smoke? Was the impeller burning?
- Why there was no obvious pink stuff coming out, but what looked like dirty pink?
Any advice is greatly appreciated.
